Knowledge engineering refers back to the course of of making and sustaining buildings and methods that acquire, retailer, and rework information right into a format that may be simply analyzed and utilized by information scientists, analysts, and enterprise stakeholders. This roadmap will information you in mastering numerous ideas and instruments, enabling you to successfully construct and execute various kinds of information pipelines.



Containerization permits builders to bundle their purposes and dependencies into light-weight, transportable containers that may run constantly throughout totally different environments. Infrastructure as Code, then again, is the apply of managing and provisioning infrastructure via code, enabling builders to outline, model, and automate cloud infrastructure.

In step one, you’ll be launched to the basics of SQL syntax, Docker containers, and the Postgres database. You’ll discover ways to provoke a database server utilizing Docker regionally, in addition to how you can create an information pipeline in Docker. Moreover, you’ll develop an understanding of Google Cloud Supplier (GCP) and Terraform. Terraform will probably be notably helpful for you in deploying your instruments, databases, and frameworks on the cloud.



Workflow orchestration manages and automates the stream of knowledge via numerous processing phases, akin to information ingestion, cleansing, transformation, and evaluation. It’s a extra environment friendly, dependable, and scalable manner of doing issues.

In thes second step, you’ll find out about information orchestration instruments like Airflow, Mage, or Prefect. All of them are open supply and include a number of important options for observing, managing, deploying, and executing information pipeline. You’ll study to arrange Prefect utilizing Docker and construct an ETL pipeline utilizing Postgres, Google Cloud Storage (GCS), and BigQuery APIs . 

Try the 5 Airflow Alternatives for Data Orchestration and select the one which works higher for you.



Knowledge warehousing is the method of amassing, storing, and managing massive quantities of knowledge from numerous sources in a centralized repository, making it simpler to research and extract helpful insights.

Within the third step, you’ll study all the pieces about both Postgres (native) or BigQuery (cloud) information warehouse. You’ll study concerning the ideas of partitioning and clustering, and dive into BigQuery’s greatest practices. BigQuery additionally supplies machine studying integration the place you’ll be able to practice fashions on massive information, hyperparameter tuning, function preprocessing, and mannequin deployment. It’s like SQL for machine studying.



Analytics Engineering is a specialised self-discipline that focuses on the design, improvement, and upkeep of knowledge fashions and analytical pipelines for enterprise intelligence and information science groups. 

Within the fourth step, you’ll discover ways to construct an analytical pipeline utilizing dbt (Knowledge Construct Device) with an current information warehouse, akin to BigQuery or PostgreSQL. You’ll achieve an understanding of key ideas akin to ETL vs ELT, in addition to information modeling. Additionally, you will study superior dbt options akin to incremental fashions, tags, hooks, and snapshots. 

Ultimately, you’ll study to make use of visualization instruments like Google Knowledge Studio and Metabase for creating interactive dashboards and information analytic reviews.



Batch processing is an information engineering method that entails processing massive volumes of knowledge in batches (each minute, hour, and even days), relatively than processing information in real-time or close to real-time. 

Within the fifth step of your studying journey, you’ll be launched to batch processing with Apache Spark. You’ll discover ways to set up it on numerous working methods, work with Spark SQL and DataFrames, put together information, carry out SQL operations, and achieve an understanding of Spark internals. In the direction of the top of this step, additionally, you will discover ways to begin Spark situations within the cloud and combine it with the information warehouse BigQuery.



Streaming refers back to the amassing, processing, and evaluation of knowledge in real-time or close to real-time. Not like conventional batch processing, the place information is collected and processed at common intervals, streaming information processing permits for steady evaluation of probably the most up-to-date data.

Within the sixth step, you’ll find out about information streaming with Apache Kafka. Begin with the fundamentals after which dive into integration with Confluent Cloud and sensible purposes that contain producers and shoppers. Moreover, you have to to find out about stream joins, testing, windowing, and the usage of Kafka ksqldb & Join. 

When you want to discover totally different instruments for numerous information engineering processes, you’ll be able to discuss with 14 Essential Data Engineering Tools to Use in 2024.



Within the last step, you’ll use all of the ideas and instruments you’ve discovered within the earlier steps to create a complete end-to-end information engineering undertaking. It will contain constructing a pipeline for processing the information, storing the information in an information lake, making a pipeline for transferring the processed information from the information lake to an information warehouse, remodeling the information within the information warehouse, and making ready it for the dashboard. Lastly, you’ll construct a dashboard that visually presents the information.



All of the steps talked about on this information may be discovered within the Data Engineering ZoomCamp. This ZoomCamp consists of a number of modules, every containing tutorials, movies, questions, and initiatives that will help you study and construct information pipelines. 

On this information engineering roadmap, we’ve got discovered the varied steps required to study, construct, and execute information pipelines for processing, evaluation, and modeling of knowledge. We’ve additionally discovered about each cloud purposes and instruments in addition to native instruments. You possibly can select to construct all the pieces regionally or use the cloud for ease of use. I might suggest utilizing the cloud as most corporations want it and need you to achieve expertise in cloud platforms akin to GCP.
